摘要: 试验研究了不同氮肥施用量对翠冠梨芽苗生长的影响,在少量多次的施肥方式下,统计了不同氮肥水平下翠冠梨芽苗各个时期的株高、径粗以及叶片数。结果表明,在高中氮水平下,6个时期的翠冠梨芽苗株高、径粗、叶片数总体均为最高。综合各项指标,确定每株翠冠梨芽苗施氮肥300 g,分4次平均环状沟施,最有利于翠冠梨芽苗的生长。

Abstract: The effects of different amount of nitrogen fertilizer on the growth of Cuiguan pear bud seedlings were studied by a small amount of multiple fertilization method. The plant height, stem diameter and number of leaves of Cuiguan pear bud seedlings at different nitrogen levels were determined. The results showed that under high and medium nitrogen level, the plant height, stem diameter and leaves number during the six periods were the highest on the whole. According to various indexes, it is determined that the nitrogen fertilizer of per plant was 300 g, and the average annular ditch was divided into four times, which was most beneficial to the growth of Cuiguan pear bud seedlings.

Key words: nitrogen fertilizer, arm antegrade, Cuiguan pear, bud seedling
